UNITED STATES PATENT EricE.

HARRY C. MOOARTY, OF WILLIAMSPORT, ASSIGNOR OF ONE-HALF TO JOHN F. BICKEL, OF MORTON, PENNSYLVANIA.

CAR-TRUCK.

ESPECEFICATION forming part of Letters Patent No. 31%,459, dated March 2%, 1885.

(No model.)

o all whom t may concern,.-

Beit known that I, HARRY C. MCOAETY, a citizen of the United States, residing` in the city of iVilliainsport, county of Lycoming,and State of Pennsylvania, have invented a new and useful Improvement in CarTrueks, which improvement is fully set forth in the following specification and accompanying drawings, in which- Figure l is a side elevation of a car-truck Fig. 2 is a partial end View and partial transverse section there- IAS of' in line x x, Fig. l. Fig. 3 is a partial top View and partial horizontal section thereof in line x x', Fig. 2. Fig. 4 is a vertical section ot' a detached portion inline yy, Fig. 2. Fig. 5 is a vertical sect-ion of a portion in line z z, Fig. 8. Fig. 6 is a vertical section of a portion inline z e', Fig. 3.

Similar letters of' reference indicate corresponding parts in the several lign res.

My invention consists ot' a bolster of atruck more especially designed for a freight car, which is strong and durable, as will be hereinafter fully set forth.

Referring to the drawings, A represents the side trusses of a car-truck, the same being formed ofthe upper pair ot irons, A A, and the lowerpair ot irons, A.A, the boxes being fitted between the ends of' the two pairs ot' irons.

interposed between the arched or central portions ofthe irons A A are bars B B, of angle or channel iron, which are secured to said irons by means of bolts B', which are passed through theupperirons, A', the flanges of the bars B, the lower irons, A", and also through the irons A, and tightened by the nuts a., thus firmly connecting said irons and bars.

The spring C rests partly on the upper irons, A", and partly on supports C', which are se cured to the angleAirons or bars B, said supports and irons forming broad surfaces to sustain the springs.

The angle irons or bars B stiften and strengthen the side trusses, and are also serv iceable as means of connection of the brakerigging with the truck.

D represents a bolster whose ends are sus tained on the springs C, the same being formed ofthe top arched bar, D', and lower iron bar, D", which are connected bythe bolts E, the latter passing throughsaid bars D D" and columns D', rising from the bars D',and tightened by suitable nuts.

Secured to the under side of the bolster, at the ends thereof, are castings or heads F, which are fitted to the top of the springs O, and serve to guide the bolster and hold the springs in position.

interposed between the hars Dl D" of the bolster, at the centers thereof', are bars or angie-irons G, which are bolted to said bars firmly and securely connecting the same, and strengthening the center of the bolster, whereby it is well enabled to sustain the load to which it is subjected, the center plate, H, being also bolted or otherwise firmly connected 'with the bolster, the bolts F' passing through iianges of the bars or angle-irons G, and the lower bars, D", forming a strong structure.

The ends of the4 har D" are turned back, forming laps D', against which the ends of' the upper bar, D', are thrust as abutments, thus increasing the strength of the end connections of the two bars.

The term angleiron above employed also embraces shapes of iron known as channelbars.

Having thus described my invention, what l claim as new, and desire to secure by Letters Patent, is-

l. ln a car-truck, the side trusses consisting ot' irons A' A" A' A'', in combination with the angleirons B. cach of' which extends across the space between the upper irons, A and A, and the bolts B', which pass through the fianges of said anglc-ironsand also through irons A', A, and A, substantially as set forth.

2. In a cartruck, a. bolster consisting of upper and lower bars and supporting angleirons between the bars, said angle-irons being parallel to said Lipper and lower bars and tially as and for the purpose set forth.

3. The upper bolstcr-bar, D', having horizontal ends, in combination with the lower bolster-bar, D", having` its ends extended beyond the ends of the bar D', and folded back against them, these two bars composing the whole bolster, substantially as shown.
